Patent number: 9541142Abstract: In some embodiments, a redundant control system includes first and second control systems, having first and second clutches, and a shared clutch system. The shared clutch system may include a shared shaft configured to receive mechanical energy from a shared power source, a first shared clutch corresponding to the first clutch and configured to receive mechanical energy from the shared shaft, and a second shared clutch corresponding to the second clutch and configured to receive mechanical energy from the shared shaft. A first linkage provides mechanical communication between an output of the first clutch, an output of the first shared clutch, and a first output device in mechanical communication with the rotor system. A second linkage provides mechanical communication between an output of the second clutch, an output of the second shared clutch, and a second output device in mechanical communication with the rotor system.Type: GrantFiled: September 10, 2014Date of Patent: January 10, 2017Assignee: Bell Helicopter Textron Inc.Inventors: Pasquale Spina, Carlos A Fenny, Jean-Sebastian Plante, Patrick Chouinard, Jean-Philippe Lucking Bigué, Yves St-Amant

Publication number: 20160221674Abstract: According to one embodiment, a trim actuator for a pilot input device includes a driven member and a driving member configured to receive mechanical energy from a power source. A magnetorheological (MR) fluid is disposed between the driving member and the driven member and configured to transmit a variable amount of mechanical energy from the driving member to the driven member such that the driven member moves in a first direction. An output member configured to be coupled between the driven member and the pilot input device. A spring is in mechanical communication with the output member and configured to apply a force in a second direction opposite of the first direction. A magnetic circuit is configured to control movement of the pilot input device by varying the strength of a magnetic field delivered towards the first MR fluid.Type: ApplicationFiled: December 7, 2015Publication date: August 4, 2016Applicant: Bell Helicopter Textron Inc.Inventors: Geoffrey C. Latham, Albert G. Brand, Jean-Sébastian Plante, Guifré Julio, Marc Denninger
